This European Standard specifies the term bio-lubricant and minimum requirements for all kinds of bio-lubricants and bio-based lubricants, while e. g. the EEL refers to specific bio-lubricant families. This European Standard also briefly describes relevant test method needs with respect to the characterization of bio-lubricants. It presents recommendation for related standards in the field of biodegradability, product functionality and the amount of different renewable raw materials and/or different bio-based contents used during manufacturing of such bio-lubricants forming one product group. WARNING - Not all potential risks for the environment can be addressed by this standard.
